How to Choose YO Coil Sizes for Book Loose-leaf Binding – Professional YO Coil Selection Guide for Book Printing

1. Classification of YO Coils for Book Binding

YO coils for commercial book printing are classified by material, shape and opening direction, adapting to different printed book thickness and usage frequency:

• Material Classification: Metal YO coils and plastic PVC YO coils. Metal coils feature high hardness and anti-deformation, suitable for thick textbooks and long-term use books; PVC coils are lightweight, cost-effective and colorful, ideal for notebooks and promotional printed books.
• Shape Classification: Single-loop round YO coils and double-loop flat YO coils. Round coils are more flexible for frequent flipping, while flat coils save space for stacked book storage.
• Opening Style: Side opening and top opening, matching horizontal and vertical layout book printing designs respectively.
